application filed April 18,

To all whom it may concern;

Be it known that JULIUS Jrronnson, citizen of the United States, and resident of the city of New York, in the county of Bronx and State of New York, has invented cer- Driers, of which the following is a specification.

This invention relates to driers. One object thereof is to provide a drier with practical heat drying apparatus in which the heat vehicle does not come in contact with the clothes or materials to be dried and a yet afiords eflicient and efiective drying.

e Other objects or this invention will a part be obvious and in part hereinafter Leo "Patent Oliice' April 4th, 1921..

Another object of the invention is to provide a drier of the character described with practical and eflicient means whereby the moisture evaporated from the materials or clothes to be dried is readily and efiectively abstracted from the drying. chamber or cabinet simultaneously wit the expulsion therefrom of the heat vehicle.

Another object is to provide a drier. of the character described which is eficienh in operation and simple and cheap in construction and economical of heat energy to a high degree.

Certain features herein shown and described are shown, described and claimed in 'my co-pending aplication for Patent Serial No. 458,314, w in the United States With the above exception, the invention accordingly consists in the features of construction, combinations of elements and arrangeme nt of parts which will be exemplified 1n the construction hereinafter described and of which the scope of invention will be indicated in the following claims.

- dicates the drying cabinet comprising the sidewalls 10, rear walls 11, and the top 12. The rear walls 11 are made preferably of two independent sheets of material 13 and 14 so .as to enclose the air space lotherebetween and suitably joined to each other at the slde edges thereof as at 16. The side walls 10 are similarly construed of two sheets of metal 31, 32enclosing an air space 33 therebetween. The top 12 (not shown in detail in the drawing) is joined to the side and rear walls and may be of double-wall construction similar to the side and rear Wall'so'as to include an air space, For 76 holding the sides 10 together'and niaintaining the rear walls suitablemeans such as straps or brace members 17 are provided. A drying rack 18 is arranged on a frame- 18 for movementin and out of the cabinet so that therack bars 19 ma be loaded with the materials or clothes to be dried or such materials removed asjdesired.

The apparatus for supplying the necessary heat to the'cabinet in order to dry the materials' or clothes placed therein and for ab stracting themoisture from the cabinet will now be described. Located preferably on the outside of the cabinet is a furnace box 20 in which is enclosed a suitable heating element (not shown) such as steam pipes, electric coils or gas burners. The heat vehicle such as air is heated by this heating element and led from the furnace box into a closed chamber 21 located preferably near to the bottom of the dryin cabinet. A suitable opening 22 is formec in one side 22 ofthe chamber and provides the communication between said chamber and the furnace box 20. The chamber is supported inside of the cabinet on standards or legs 23 or in any other suitable manner. In the embodiment shown in the drawing, the chamber is formed from one piece of sheet metal to prov vide end walls 22", 22, and a top 22 thus 1% forming a completely enclosed rectangular chamber, except for the opening 22" where communication is established etween it and the furnace box. Leading from one end of the chamber is a fine 24 for the purpose hereinafter described and located within the chamber are a series of bafie plates such as 25, 26 and 27 extending obliquely across this chamber 21. One of these baiiie plates such as 25 is located at and extends from the wall 28 of the opening 22 which is nearest to the end ofthe' chamber from which extends the exhaust flue 24 so that as the heat vehicle enters the chamber it strikes against the baffle 25 and is thus directed towards the end of the chamber remote from the flue 24. The fine 24 is interrupted by the vent box 29, one of the faces of which, preferably that facing the opposite end of the chamber has openings 30 formed therein for the purpose hereinafter described. 4

The operation of the heating apparatus and the moisture abstracting apparatus will now be clear. As the heat vehicle enters the chamber from the furnace box 20, it strikes the baflie plate 25 and as already explained is directed away therefrom to the end of the chamber remote from the flue 2d. The heat vehicle circulates in the direction of the arrows shown in Fig. 1 through the chamber, its velocity being retarded by the baflies 26, 27. When the heat vehicle reaches the opposite end or flue end of the chamber, it is drawn out through the flue 24. In passing thrbugh the flue, a draft is created across the vent box 29 and the moisture evaporated from the materials to be dried in the form of aqueous vapor is drawn through the openings 30 and readily car ried out through the flue. It will be noted that the heat vehicle does not come in contact at all with the clothes or materials to be dried, the heat chamber 21 being comletely enclosed as shown in Fig. 2, the

eat being transmitted to the materials in the cabinet by radiation from the chamber 21 and also by convection currents of the air in the cabinet outside of the chamber. The baflles insure a slow and thorough circulation of the heat vehicle within the-chamber from one end thereof to the. other, and a given volume of heat vehicle supplied to the chamber is held therein for a suflicient length of time to give the desired radiation and convection efiects for thoroughly evaporating the moisture from the clothes or materials to be dried. At the same time, the heat vehicle in itself does not come in contact with the clothes or materials, and these are not afl'ected by the fumes or other vapors that usually are mixed with the heating vehicle due sometimes to the furnace or other method by which heat is imparted thereto, and thus avoidin oxidation of or staining or otherwise disco o-ring-the clothes or materials to be dried. i

It will thus be seen that there is provided apparatus in which the several objects of this invention are achieved and which is Well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the neiaaea accompanying drawings is to bb interpreted as illustrative and not in a limiting sense.

Havingv thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a drier, a drying cabinet for the materials to be dried, a heater for imparting heat to a heatvehicle, a heating chamber located in said cabinet, said chamber having an opening communicating with said heater whereby the heat vehicle passes from the latter into the chamber, means at one end of the chamber for exhausting the heat vehicle therefrom, and means in said. chamber for retarding the circulation 'of the heat vehicle therethrough.
